Tabs 13 and The lines 28 and 29 are equal to the space between the ends of the flat position indiated in dotted along "face of the panel spaced a distance panels 3 and the scored lines 12, so that when the corner 31 isfolded inwardly from the lines to the folded position as shown infull lines at the right of Fig. 2 of the drawings, a triangular end piece is formed.having a flat hypotenusal edge 33 adapted to match with the end portion of the panel 12 when said end piece is turned upwardly as indicated in the partially folded portion of the blank at the bottom of said Fig. 2.

. The blank, cut and scored in the man ner shown and described, is folded to form the shipping case in the following manner. The end panels 4 and 4: are first bent upwardly along the scored lines 9 and the hypotenusal panels.l2 folded upwardly along the lines 8 until'the edge of the previously folded panels 4 and 4 are moved againstth scored lines 7. In this relation the panels 2 and 4: correspond to the legs of a right triangle, the hypotenuse of which is defined by the panel 3, thereby forming a prismoidal case section at each end of the blank.- The triangular tabs 11 are then bent inwardly along the lines 12 to extend across the ndsof thepris moidal sections, said tabs, being shaped to conform to the triangular form of said sections. The points of the tabs 11 engage the notches 19 and slts 34 formed in corresponding position across the juncture of the panels 1 and 2, said notches and slts being adapted to hold the tabs 11 in spaced parallel relation to the ends of the prismoidal sections. The tabs 13 and-14 are bent outwardly along the lines 8 and 9. The end pieces formed by the extensions 24, are then moved to close the ends of the sections, said extensions having the corners 31 first folded inwardly into engagement with the slit: 2%2 a then folded upwardly to close the ends of the sections.-

of thetabs are introduced through the pairs of slts 2-1 and 22, as shown in Fig. 4, thereby efi"ectually securing the end pieces in end closing position.

From the position above described, the prismoidal sections are turned inwardly the lines 7 to the open case position shown in'Figs. 1 and 6. In thus moving the sections, one of the sections is first turned inwardly as shown in Fig. 5, the outer sur- 4 being moved-into matching contact with the panel 1. The tab 14 extends over the adjacent panel 1, while the tab 13 extends upwardly from the top edge ofthe prismoidal section as shown at the right in said Fig. 5 of the drawings. The other prismoidal section is along-its line of fold7 f.iomthe position shown in full lines to the position indicate fold 9 matching with the line 6 then turned inwardly d tion. The double 0 in light dotted lines. As the latter section is thus moved, the tab 14 is introduced upwardly through the slit 18 in the panel 4, and as said section is further moved, the tab 14 carried thereby is introduced downwai*dly through the slit 18 in the panel 4 of the first moved section, said tabs being thus caused to interlck across the bottom of the case and thereby hold the lower edges of the prismoidal sections together in what is termed the open case'position as best shown in Fig. 6 of the drawings. In this relation it will be seen that my improved case consists of two prismoidal sections having opposite open hypotenusal faces, resulting from the displacement of the tabs 11, 13, and 14, from the hypotenusal panels 3, and joined along their adjacent. edges.

From the open case positions above described, the sections are moved to closed relation b turning one of the sections upwardly along .t ie center line of fold 6, to the closed position shown in heavy dotted lines in Fig.

'5 and in full lines in Eigs. 2 and 7. The overlapping tabs 14 have their scored lines of so that said tabs reinforce the panels 1 and cooperate with the fold between said panels 1 to permit a hinge like movement between said sections.

As the sections are moved to closed relation,

the tab 13-of one section is moved outwa rdly through a slit 36 formed in the panel 2 of the opposite section, and the tab 13 of said opposite section is moved to 'engage and extend inwardly through the corresponding slit 36 in the first section as shown in Figs. 2 and "7. In this mnner, the tabs 13 secure the two prismoidal sections together at their free edges with their hypotensal faces in proximate juxtaposition, thereby forming a -case of rectangular cross section,.having a rectangular packing space therein. To seal the case in closed relation for shipping, an

'adhesive strip 37 is extended over the tabs 13 and the adjacent surfaces of the panels 2, said strip preferably being extended entirely around the case as shown in Fig. 2.

In packing or unpacking the case, the sections are moved to open position, thereby per- .mitting goods to be readily stacked or removed from one section, each section being entirely Open across the top and one side. The goods are stacked in one section to occupy the full rectangular space, as shown in Fig. 1, the opposite section serving to fully cover the goods when said section is moved to closed position. Y 4

My improved packing case is extremely rgid, as the triangular end pieces, cooperating with the tabs 11 form a double walled end which is reinforced by the comer portions 31as best shown in Fig. 8 ofthe drawings,'thereby giving strength and rigidity and eifectually maintaining the sha e of each sec- 1naterial extending substantially entirely around the case gives both strength and rigidity and efl'ectually protects the case and its contents from injury in ordinary service. The case may be used repeatedly as it can be opened and unpacked without injfury to the case.

My improved shipping case,- while adapted for use in a great number of ways, particularly for the shipment of fragile articles, is especially useful for the packing and shipping of eggs and the like previously packed in small cartons such as disclosed in my copending application, Serial Number 223,909, filed October 4, 1927.. By use of my improved carton and shipping case, eggs may be packe'd and safely shipped by the producer directly to the market, thereby avoiding the repacking commonly resorted to, and inuring the identity of the product sold.

While I have illustrated and describedonly the preferred embodiment of my invention the device is, of course, subject to modification in numerous ways without departing from the spirit of my invention. Y I therefore do not wish to restrict myself to the specific details of construction, myself of all modifications which may fall within the scope of the appended claims.
